SHEETQMETAL HANGER.

Application filed February 5, 1920, Serial No.`356,439. Renewed September 8, 1923. Serial No. 570,382.

To all whom t may concern:

Be it known that EDWIN HUGH ARABA, citizen of the United States, residing at Mishawalra, in the county of St. Joseph and State of Indiana, has invented certain new and useful Improvements in Sheet-Metal Hangers, of which the following is a speciication.

My invention relates to improvements in sheet metal hangers and it more especially consists of the features pointed out in the. annexed claims.

The purpose of my invention is to pro` vide a light-weight hanger that is very strong; that consists of few parts; that lends itself to economic and rapid production; and

that will successfully meet the practical conditions of the most exacting service.

With these and other ends in view I illus-v trate in the accompanying drawings such instances of adaptation as-will disclose the broad underlying-features without limiting myself to the exact details shown. Y

Fig. 11 Sheet V3 is a section of Fig. l0 on Fig. 14 Sheet 1 is a detached perspective of a beveled angle plate.

Fig. l5 Sheet l is an end elevation of a square recessed nut.

Fig. i6 Sheet 3 instances alternatives d., B and C as substantial equivalents of full depth flanges formed on both halves of a hanger body. Y

In carrying my invention into practice, economy and rapidity of production is provided for'by making the two halves of a hanger body. substantially duplicates of each other and assembling them in coordinate relation to each other so that an open hollow interior is secured and coacting parts are formed adjacent each other on opposite sides of the hollow interior.

This is done by taking a Sheet l and blanking it approximately as shown .in Fig. 2, Sheet 2 by means of dotted lines. Flanges 2 are shown in full lines. These occur along the main hanger edges. The body members are wider at one end than the other. At the narrow end a slotis formed between` two 'forks 5. rlhe inner flanges of the forks are indicated by 3 and a transverse flange t almost spans the width of the slot 7. An

opening 6 is formed above the slot 7, leaving a cross piece il which separates the one from the other. Flanges 8 project from the edges of opening 6.

The widest portion of the body 'l is provided with feet 29. This end of the body may be uppermost, when used as a hanger. or lowermostwhen used as' a pedestal bearing support-.1 l't is quite immaterial in what position the hanger is placed, vertical or in'an angular relation to these. The feet 29 have a flat portion 9 against which the usual lag screws or fastening bolts abut.- The feet 29 are provided with internal reinforcements 30 vand 34 shown in Fig. 9. rlhe reinforcement 30 passes around the fastening bolts 35and by means of projections 31 is secured by spot welding, or otherwise'to the'bodv parts 1. VOn each side of the loop 30 Vlateral reinforcements 34 are placed; These till the space. edge wise, between the bearingP` part of the feet 'engage the flanges 2 and projections 32 Sti titl

of sheet steel by various blanking and forming operations-so as .to make a very light,\ V

strong and rigid structure.

The, fork'parts 5 that project on each side rof the slot 7 are provided withslotted'holes 10 that accommodate horizontal set screws 15 formed in the outer flanges 2 and the inner .flanges 3. Between these flanges square distance nuts 17 having a threaded opening and a recess 18, are placed.

A The set screws pass through these nuts so that the inner .ends engaoe opposite sides of the bearing 13 .zo

ofshaft 3 thus ina-king it possible to ad` just.l the shaftA on the plane of these set [screws and when `'so adjusted lock nuts 16 holdthe` set screws against accidental or other unintended displacement. A. similar nut17 isfplaced'adjacent ,the cross-piece 41 i and Abetween flanges ..4 and 8 to receive set screws 14. ASlots 11 and 12 in these flanges 4permit of lateraly adjustment and the set screw f14,1ocked by 'nut 16 determines the '3Q vertical .position ofthe bearing 13 and also of the set screws 15 which pass through i'at slots 10. The'open end of the slot 7 Vis closed by astampedfupgbar 19 shown in Fig.12.Sheet 1. j It hash'oles .2O at each end forv bolts 22 that passthrough holes 20 ,ofthe forks 5.

This arrangement permits the easy placementof ashaftf37without threading the hangersover` along shaft.4 A nut 17 is placed inside ofthe bar 19 between its lower wall 247 upper wall 26,and sidewalls 23. A' set screw `14 passes through `this nut and slots 21formed-in/the upper and lower parts 26and 24 respectively of the bar 19. .The

ends of the upperpart26 arecut away at 27 to accommodate the forks 5. This bar is 'also formedwith a single piece of fla-t metal, thus `*making a verystrong, yet light structure.

is'bevelled ofi". at'25 to eliininatesharp corners.. and .the forks are .bevelled accordingly. This leaves ancpeninggat the lower; end of the Yforks which isclosed by the inser-` tion of beveled angle plates 28' shown in Fig.

14 Sheet 1.

lIt `will be seenE that the duplicate halves 1 ywith the respective `anges. arewsimply as Vsembled so` that the companion flanges over# `lap each other. They-areso held by :spot

orcontinuous welding or. any `otherway to yform a structurally integral unit of great strength. `It is however plain Athat certain` I ,mo'dificationsmay fbe.used, instead of the flanges. 2,;fSome of these alternatives are ,65. shownin Fig. 16 vwherein at A Va distance:v

strip 39 isinstaneed which may bejwelded figure show variations edgewise to the bodyparts 1. AtB a sepaa distance piece 3 9 overlaps these flanges, onv

the inside or outside (not shown)'so as to hold the parts together through electric welding or otherwise. In any event great economies in production are secured by making the body parts in duplicate. Should the alternative -shown at-C of Fig. 16 be used oreither-of the other substitutes, not all ofthe flanges 2 would need to be replaced. Freedom of .selection would determine the relation the respective forms should bear to each other.

In Fig. 1 a foot is at the left hand side. cation but an adaption of the same type of feet for shorter hangersLGther positions may be selected for still'shorter types. VLikewise the dotted shaft lines of this same in positionof the shown in dotted lines Vshaft 37.. Y

It is to be understood that the use yof rivets etc., to'holdv Vduplicate'parts together instead of welding the'saine comes within the scope of my present invention which in its fbroade'st sense comprises the grouping of .duplicate halves `to form a hollow hanger This is not a modifi structure regardless of the specific contours, f

shapes, etc., that the various'parts may assume. j

What I'cla'imisz:` n 1. In sheet metal hangers, Vstamped-up duplicate halves provided with edgewise flanges, and means for holding them assembled-with the flanges ofV one half overlapping thosefof the otheruhalf inalternative some of the edgesthereof, ineaiisffor assenibling the halveswithcoacting flanges in face to face Contact with eachother in alternative inside vand `outside vlrelation. and,

-meansfor holding'-y the assembled lparts in rigid i'relationtoeach other. Y 4. In sheet metal hangers..duplicate'body parts 'having a portioniof their edges provided. with'projecting flangesfadapted to be assenfibl'edV with the anges inv a sidelby-side alternative internal and external relation,

suitable feet secured tol thebody'parts at one end thereof; and bearing supporting members secured to fthe other end of the 1 body `parts toA formf a hollow reinforced vshaft supporting structure.

5. In shaft hangers, duplicate sheet metal body parts formed with flanges which project from a portion of the edges of each body part and adapted to cooperate with each f.V other in alternative inside and outside relation, said body parts having a shaft bearing opening at one end thereof, suitable feet at the other end, and removable means for closing the said opening after a shaft bearing is in position therein and adapted to be opened to also admit placing the shaft bearing into position in the opening or removing the same therefrom.

6. In shaft hangers, duplicate sheet metal parts having alternatively positioned flanges constituting the body portion of a complete hanger, a shaft opening at one end, a stamped removable closure member for such opening, widened-out stamped feet attached to the other end of the body parts, and means for holding all the parts in assembled relation.

7. In shaft hangers, a sheet metal body portion composed of duplicate stampings,

formed'wider at one end than the other, a slotted opening at the narrow end, an isolated opening adjacent the slotted opening, a removable stamped closure for the eXtreme termination of the slotted opening, separate pressed sheet metal feet at the wide end of the body, internal reinforcements for said feet, flanged edges of said body portions adapted to be assembled so that the flanges of one half of a body portion overlap the flanges of the other half of the body, and means for holding the body and feet in substantially integral assembled relation.

8. In shaft hangers, a hanger body formed by two flanged principal sheet metal members so as to enclose a hollow rectangular interior, and means for holding such members in assembled relation with the flanges of one half in alternative inside and outside position with respect to the flanges of the other half.

In testimony whereof I aiX my signature.
